The next time you think about making that cocktail a double, wait—it might already be one.
William Kerr, along with colleagues from the Alcohol Research Group at the Public Health Institute, took a scientific bar crawl—no, not the kind where you visit science-themed drinking establishments. The researchers visited 80 places in northern California, mostly bars and restaurants, to find out the alcohol content of their drinks—by analyzing them, not by partaking. Compared to the scientific standard of one drink—12 ounces of beer, 5 ounces of wine, or one and a half ounces of 80-proof liquor—the bars and restaurants were pretty generous with their liquor, giving out stronger booze than the researchers expected, and more of it.

A good week for drinkers may have just gotten better.
